Question

Casey waited tables this summer. On Monday , she made $60. Each day , her pay decreased by $4. What integer represents the total change in her pay over a 5 - day period ?

Answer 1

The answer is $260 first you do 60-4 that equals 56 and then you do 56-4= 52 and you do 52-4 = 48 then 48-4=44 then you do 60+56= 116 and then you do 116+52=168 and then do 168+48= 216 and then 216+44=260 the answer is 260

Answer 2

The integer that represents the total change in her pay over a 5 - day period is '20'.

Explanation:

On Monday , Casey made $60.

Each day , her pay decreased by $4.

So, in 5 days the value decreased by
`4*5=20` dollars

So, total change was 20.

We can also say its negative because there is a decrease in the value.

Hence, the integer that represents the total change in her pay over a 5 - day period is '20'.
